is it normal missing modules?

generally this is due to the power-on sequence. I see it all the time in the various modules I test. I haven't found a good way to avoid it. I don't think it is necessarily related to your soldering skills, but it maybe related to parasitic capacitances. In any case, it is not uncommon.

what version of deviation are you using? I switched from using the reset pin to a different reset sequence. That may have some affect on an unmodified tx.

if you don't have a multimodule, you could try disabling the multimodule support and see if that helps. That may help identify a software issue. I don't recall the problem being common on Deviation 4.0.1. Or try running 4.0.1 and see how that behaves.

other than that, I'm not sure how to debug. this has infuriated me because as soon as I install a logic analyzer, the issue goes away, so I can't actually debug.
you could also try using 'force=1' in the [modules] section of the hardware.ini.
That will prevent the modules from disabling even if they aren't detected. if communication still works, that would imply that the module detection doesn't work reliably.
